Abstract: ABSTRACT OF THE DISCLOSURE This disclosure is directed to a method of break-ing an oil-in-water emulsion.  Briefly, the method includes the steps of adjusting the pH of the oil-in-water emulsion to a pH in the range of 6 to 10.  At least one part per million of a cation selected from Fe+2, Fe+3, Al+3, Cu+1 and Cu+2 is added to the oil-in-water emulsion.  Thereafter, the oil-in-water emulsion is treated with a dissolvable iron electrode, the electrode being dissolvable by trans-mitting an electric current thereto.  Sufficient electric current is transmitted through the electrode to develop a ferrous ion/oil weight ratio of at least 0.02.  After treatment by the dissolvable electrode, the oil-in-water emulsion is held until the emulsion breaks.

Abstract: MISCIBLE DRIVE IN HETEROGENEOUS RESERVOIRS                      ABSTRACT OF THE DISCLOSURE A method of improving the  sweep efficiency and increasing oil recovery of miscible flooding without reducing injectivity of the injec-tion wells.  Two sets of wells are used  with one set being drilled bet-ween the other sets.  The interwell area of a reservoir is pretreated by injecting a  permeability-reducing agent (preferably a  polymer) through said first set  of wells.  The polymer  enters the more  permeable zones and partially plugs them,  both near and away from  the wellbore.  Ther-eafter, the injection  or first set of wells are  converted to producing wells.  After the step of reducing the permeability contrast of the het-erogeneous reservoirs, a miscible slug, that may or may not be  preceded by a  controlled salinity preflush, is  injected into the second  set of wells.  There is  no reduction in injectivity of  the miscible injection wells, because no permeability-reducing agent has been injected thereth-rough.   Reduced permeability  contrast results  in improved  volumetric sweep efficiency and increased oil recovery  by the miscible fluid slug. The method is particularly useful in  reservoirs with communication bet-ween various permeability zones where crossflow  of fluids can be detri-mental to flooding efficiency.

Abstract: 20,466 APPARATUS AND METHOD FOR FREQUENCY CHANNEL     SELECTION IN A RADIOTELEPHONE SYSTEM     Abstract In a mobile radiotelephone system, N separate modulated carrier sig-nals in N frequency channels are applied to a demodulating radio receiver which provides a succession of N different output signals each having idle and busy states.  An idle and signal-to-noise detector monitors each of the output sig-nals of the radio receiver.  The detector provides a first logic signal when one of the output signals concurrently exhibits an idle state and has at least a predetermined minimum signal-to-noise level, and provides a second logic signal at all other times.  A receiver switching circuit, in response to the second logic signal, causes the receiver to cyclically switch to each of the N frequency channels.  When the receiver switches to a carrier signal which causes the detector to produce a first logic signal, the switching circuit causes the receiver to lock onto that particular carrier signal.  Improved operation results from a gain control circuit which reduces the gain sensitiv-ity of the receiver upon a change in state of the detector output signal from a first logic signal to a second logic signal.  The gain sensitivity is then slowly increased as the receiver cyclically switches to each of the N frequency channels.  When an idle receiver output signal is detected having at least the minimum level of signal-to-noise, the receiver switching circuit locks the receiver onto the particular carrier signal.  This technique assures that the first such detected signal will provide the best frequency channel for the demodulating radio receiver.

Abstract: SAFETY BRAKE MECHANISM                        FOR CHAIN SAWS     Abstract Of The Disclosure A guard member is mounted on the chain saw for swinging movement between an actuate position and a reset position.  The guard member occupies a normal position between the actuate and reset positions.  A brake band is integral with a bowed column spring which applies the braking force to arrest movement of the cutting chain.  A latching mechanism includes an arm with a latch pin engaged by a yieldable latch finger; this latch finger is integral with the bowed column spring.  The guard member deflects the latch finger in response to movement of the guard to its actuate position; this action allows the column spring to apply the brake.  The guard member is moved to its actuate position in response to a sudden movement of the chain saw, as in the case of "kickback"; this movement of the guard member is brought about by inertia or the engagement of the guard with the operator's body (most likely the wrist or the back of his hand) during this abrupt movement of the chain saw.  Manual swinging of the guard to its reset position deactivates the brake and re-establishes the latch.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention discloses a chemical analysis of a sample with reagents spotted on a fibrous or porous medium employs a medium pretreated both with reagents and with conditioning agent.  The conditioning agent increases the degree to which the liquid reactants wet the medium.  One form of pretreated medium has different reagents located predominantly within different selected zones.  Liquid is applied to the medium, typically as diluted sample, at a rate selected to enhance formation of repeatable spots.  In one embodiment the liquid is applied by flowing it onto a wick element seated on the medium. The wick is disc-like and small relative to the spot which the reactants form on the medium.  The disc can be pretreated to carry reagent, which the liquid transfers to the medium.  The analysis instrument receives a reaction medium between selectively recessed upper and lower surfaces aligned in opposition at the reaction spot being analyzed.  The analysis can, depending on the analytical reaction, the medium and the pre-cision required, proceed while the reactants are wet or can measure a reaction product after the reactants are dry.  A single point analysis can also be made.

The filter may be of the stripline or micro-strip type having a resonator constructed so that it tends to operate at a frequency different from the desired frequency, and which is not accessible for trimming after the filter is constructed.  The ground plane layer is accessible so that a portion thereof can be removed after the filter is constructed to change the electrical parameters of the line formed by the resonator and the ground plane layer to change the response frequency of the filter.  Alternatively, conducting material can be added to an opening in the ground plane conducting layer to change the response frequency of the filter.  The ground plane layer can be removed by a sand blast, laser beam or other means, and can be added by the use of conductive paint, to trim the frequency of the filter after it is constructed.
